Well, I almost read the whole post.

I agree with everybody that moves like these might be slightly +EV on the low limit SNGs.

I also have a one common situation where betting time effects my playing. It's probably leak though.

I play 4 tables, and since I'm slow , sometimes table shows up where the half of my betting time has already been used. If it's marginal push situation, and especially if I have to push crap, I just usually fold, because I'm afraid that somebody got a read from my long "thinking time".
